As long as the guys who are posting pics with their watermark proudly displayed have their RPL
Its fairly common knowledge that literally anyone with an RPL or ROC will report anyone who doesnt, Anyone investing about R300k into an ROC or just the R25k into an RPL instantly feels like they are the drone police. I see it all the time, our company operates under licence from another company who has an ROC, so there are ways to get around it, as long as the drone is registered with the company holding the ROC
Bottom line is if you don't have the correct licencing just keep your images off networks or social media, if they can track you through watermarks on your pics the CAA will,
